Mechanical Dimensional Management Engineer

Mechanical Dimensional Management Engineer

At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today's mission and stay ahead of tomorrow's threat. Our team solves tough, meaningful problems that create a safer, more secure world.

The Hardware Engineering Team provides engineering design and development services to a wide range of products within Raytheon. The Critical Item Production Readiness (CPR) department is dedicated to ensuring that every product we develop is designed with its entire production lifecycle in mind. By integrating principles of manufacturability, assembly, scalability, and cost management, we aim to achieve production excellence while meeting the highest standards of quality and reliability.

The Producibility and Dimensional Management (P&DM) section within the CPR department is seeking a Mechanical Dimensional Management Engineer, located onsite in various locations including Tucson AZ, Tewksbury MA, Marlborough MA, and McKinney TX. The Mechanical Dimensional Management (DM) Engineer collaborates directly with Mechanical Engineering, Materials and Processes, and Design and Drafting from the Hardware Engineering Team along with Operations, Quality, and Supply Chain peers, and suppliers to implement mechanical producibility improvements on new and emerging programs, and upgrades to existing programs.

The team executes tolerance optimization primarily through 3D tolerance and variation analysis and works with the design team to influence the final design. Early engagement in the conceptual stage, and throughout the development process will ensure that our designs are optimized with respect to tolerance controls and methods of manufacture. The DM engineer plays an essential part in reducing product cost and ensuring functional quality.

Occasional domestic travel may be expected. This is an onsite position.

What You Will Do

• Perform detailed and complex three dimensional tolerance analyses and review one dimensional tolerance analyses using various tools to evaluate design requirements of new and existing designs to calculate design margin / capability, and provide recommendations while adhering to cost, schedule, and manufacturing constraints.
• Work with product teams to develop coordinated datum flow and document via drawings including interface control drawings (ICDs).
• Apply, encode, and decode Geometric Dimensioning and Tolerancing (GD&T) on various technical data packages.
• Become recognized as the Dimensional Management Lead on a program to coordinate various aspects of the Dimensional Management Closed Loop Process while supporting Critical Item initiatives.
• Function as a self-starter while exercising considerable latitude in determining the strategic objectives and methods of achieving Dimensional Management goals.
• Offer assistance developing inspection plans for both internal inspection and as required by suppliers for compliance with specifications.

Qualifications You Must Have

• Bachelors in Science, Technology, Engineering, or Mathematics (STEM), and 5 years of professional engineering experience
• Experience in the application of GD&T principles (ASME Y14.5)
• Demonstrated working knowledge of statistical tolerancing methods (e.g., Monte Carlo simulations, Root Sum Squared, MRSS, etc.)
• Understanding or aptitude of kinematic principals and desire to apply to analysis and simulation of imperfect geometry within assemblies.
• Experience with CAD modeling (CREO preferred)

Qualifications We Prefer

• Experience with commercial tolerance analysis tools (Siemens VSA preferred)
• Experience with the design and/or manufacturing of high-rate production products
• Experience with design engineering of assemblies, especially exposure part to part fitment challenges and requirement definition at the assembly level.
• Working knowledge of fabrication processes, producibility enhancements, and inspection and validation methods
• Working knowledge of inspection planning, inspection methods, and dimensional data analysis
• ASME Certified GD&T Professional (GDTP per ASME Y14.5.2) or equivalent ASME standard (e.g.Y14.5) committee membership or similar involvement
• Expertise in various inspection and validation methods and tools, including gages and Coordinate Measuring Machines (CMMs)

What We Offer

• Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world. At RTX we value:
  Trust, Respect, Accountability, Collaboration, and Innovation.
